A 70-year-old Merritt Island man told detectives he was forced to withdraw his Social Security money by a man he received cocaine from, according to affidavits.

The Brevard County Sheriff's Office on Sunday charged Antwain Wilson, 36, of the 1700 block of Valley Forge Drive, Titusville, with two counts of battery on a person 65 years old or older, two counts of robbery home invasion and kidnapping.

Wilson went to the man's Ligustrum Lane home twice — on March 29 and Sunday — and forced his way inside.

Investigators also said Mistie Dawn Caldwell, 30, of the same address, joined Wilson in Sunday's home invasion. She was charged with one count of robbery home invasion.

The 70-year-old man told detectives he was a cocaine user and had met Wilson, who provided him the drug, several weeks ago, according to the affidavit. The senior citizen allowed Wilson to stay at his home as a trade-off.

But on March 29, Wilson forced his way into the man's home and demanded money for the drugs he had provided, the Sheriff's Office said. Wilson stayed at the home for several hours and would not allow the older man to leave, he told investigators.

About 2 a.m. March 30, a woman arrived at the home and drove Wilson and the resident to a gas station in Cocoa, where he was ordered to withdraw $500 cash from an ATM, the affidavit states. Wilson and the woman took the man home, but held onto his cell phone, debit card and some house keys, according to the report.

Wilson and Caldwell forced their way into the man's home early Sunday, the affidavits state. They told him they wanted to take him to the ATM machine again for more money, he told detectives. The man screamed for help, which made Wilson and Caldwell flee the scene.
